Former R.E.M. star Peter Buck has formed a new band with ex-Sleater-Kinney singer Corin Tucker.

The unnamed new group, which also features Scott MCCaughey and former Swans star Bill Rieflin, will open Buck's upcoming solo shows in Portland, Oregon this week (ends02May14).

Tucker and Buck have been longtime collaborators - she has appeared on both of Buck's solo records, while the guitarist and MCCaughey joined her onstage for a Sleater-Kinney reunion last year (13).
